Equation for Kelli's earning = 20x + 100
Equation for Karl's earning = 25x + 50
Now, 20x +100 = 25x +50
25x-20x = 100-50
5x = 50
x = 10
So, your answer is 10 hours.
Hope this helps!
Answer:
22.5
Step-by-step explanation:
What you need to do is calculate the volume of the Box. With the box being the volume of the piramid added to the prism surrounding the box with volume 15.
If you want to calculate it yourself stop reading here, because I will work it out now.
Volume box = a*b*c
Volume prism = 15
Volume pyramid = (b * c * a)/3
The prism has the volume of the box minus the pyramid so
abc - (abc)/3 = 15
abc - (1/3)abc = 15
(2/3)abc = 15
abc = 22.5
So 22.5 is the volume of the figure
Answer: $12,500
Step-by-step explanation:
Option A earnings=40*25=1,000
8/100x=1,000
.08x=1,000
x=1,000/.08
x=12,500
7^2+18^2=49+324
49+324=373
19.31^2 would be your answer
